L4400 Series Programming Examples

The L4400 series Product Reference CD- ROM (part number 34989- 13601) contains progamming examples to familiarize you with the operation of selected L4400 instruments. Once communication paths to the instruments have been set (Chapter 2), the examples can be used as an introduction to the sequence of commands necessary to program the functions available with the instruments.

The examples on the CD- ROM include multiple development environments and demonstrate instrument programming via drivers and direct programming through the I/O libraries. The drivers and I/O libraries used include:

•IVI- C

•IVI- COM

•VISA

•VISA COM

To install the examples on your computer, insert the Product Reference CD- ROM and click ‘Install’ next to “L4400 Programming Examples.” Follow the instructions as prompted.

Once installed, the examples are located in the following (default) path and are grouped into development environment directories:

C:\Program Files\Agilent\L4400\Examples

To select a specific example, open the environment directory under “Examples” followed by the driver (IVI- COM, IVI- C) or IO library (VISA, VISA COM) subdirectory.

The examples assume that you are familiar with the programming languages demonstrated and the tools associated with the development environment. Note that before you run a programming example, the program must be edited to include the address string of your particular instrument. The following sections provide instructions for editing the programs based on the driver type and development environment.

Modifying IVI-COM Examples (.NET)

IVI- COM examples are available for the Microsoft C#.NET and Visual Basic.NET development environments. To modify IVI- COM (C#) examples for use with with your instrument, open the example in the \IVI- COM subdirectory for your development environment by double- clicking the example name with the .csproj extension.
